To all whom it concern:

Be it known that I, CHARLES lb. KELLER,

a citizen of the United States, and a resident of Cincinnati, in thecounty of Hamil e ton and State of Ohio, have invented certain new anduseful Improvements in Roofing, of which the followingis a full, clear,

and exact description, reference being had to the accompanying drawing,forming part of this specification.

My invention relates to devices and shingle structures employed in thelaying of roofs, and in roofs as formed thereby. It relates moreparticularly to the provision of an interrelation between shingles andmetallic shingle securing devices, whereby a roof of adequate coverage,with each shingle 'locked down to the root at the butt can be rovided. v

t has been lproposed b'yJohn A. Topping in his Patent 0. 1,430,338,dated September 1 26, 1922, to provide a securing device for shingleswhich acts as a nailing device for shingles, and also as forming a loopor pockbe inserted, said loop spanning the top of the shingle. In myinventionl employ the I Topping devices and general method of layin 80%t is my specific object to provide a shin gle in which certain notchesand projections are formed, these serving as guiding means whereby aroof of the Topping character can be laid more expeditiously, and withgreater certainty of being uniform in exposure and roof coverage.Another object is to provide a notch in which the attaching device findsengagement, whereby considerable expan-.

et into which the butt end of a shingle can attachin referred to hereih,being that all of the shingles-are not perfectly rectangular or square.By my invention the shape of the shingle is not used as the guide inlaying, but instead the location. along the edges thereof of certainsmall notches and-pro- 'ections. These notches and projections can edefinitely spaced, .and the margin of error in the relative placing ofthe same in each shingle is very low. Accordingly by my invention 1 notonly provide a readily followed guide in laying, but I also providemeans by which inaccuracies of shape of the shingles do not hamper theaccuracy of placing them on the roof, and hence an accumulation oferror, resulting where course after course is laid following an errorwhich has arisen in a earlier course. In an ordinary shingle applicationthere is more latitude in placing of the shingles than in a roof wherethe securing device requires a definite placing of each shingle, withrelation to the ones preceding it, and hence this improvement nowrecited, is of great value in connection with roofs laid by means ofspecially formed attaching devices which demand a definite relation ofshingles throughout the roof. 7

ll accomplish theobjects above noted by that certain construction andarrangement of parts to be hereinafter more specifically pointed out andclaimed.

lln the drawing: g

vFigure 1.i s a plan view of one of the shin gles used by me.

Figure 2 is a plan view of a roof section laid according to myinvention.

Figure 3 is a perspective of devices.

The s ingle used by me is shown individually in Figure 1, having arectangular body 1, two notches 2, 2, cut into one edge, and twoprojections 3, 3, at the opposite one of the edges, the notches andprojections being a sheet, form the body of the projections on the nextadjacent shingle.

The attaching device used has two arms a, 4, ends cross piece 5, formedby a forty live degree angle bend of the metal at 6, G. The nail holes-7, 7, are used in nailing the device to the roof.

llhe roof plan has been used in some respects as a diagram for use inexplanation of a method of laying. As will be noted, the'shingles arestarted oil by a first course of shingles A, which are set at a fortylive degree angle to the cave line of the roof, with their cornerstouching each other. The attaching devices are then set in place tostraddle the upper end of the f-shapedopening between the shingles, withone leg on the corner 01 the two adjoining shingles forming the angle.The shingles oi the course B, are set with their angle points, or butts,slipped in under the portions 5 of the attaching devices.

The positioning of the notches and pro-- jections are made with relationto the size of the attaching devices used, so as to result in thefunctions to be now described.

Referring to the shingles marked D and and then through the other, willposition the attaching device or lock properly, and hold down thecorners of the two shingles through which the said lock is nailed.

lhe shingle is then applied by slipping its lower corner into the crossstrap of the lock. F to proper position since three points are providedfor. Thus the projection F will lie over the edge of the shingle D. T heedge or the shingle F will coincide with the notch D by means of whichthe attaching device was guided, has been described. The edge of theshingle l will also coincide with the position of the upper projectionif of the shine-lo 1E.

addition to the above the notch F o the shingle l will lie in theattaching do, vice, which gives the shingle F a chance l0 esp-and andcontract in normal degree without buckling, since the notch provides torsome play.

Ref rrlng to the shingle G, it will be noted that should its edges be asindicated by the dotted line G forming an obtuse angle, that thedisplacement of the upper left hand projection G would. be out of trueposition a very slight amount, this amount being mainly alon the arcof acircle having its center at the left hand corner of too shingle, whileits position along the diagonal pass- The roofer can then guide theshingle ing through the notch G and the said proection G would beadecte-d very little .lt will be noted that by my invention, we cut down"chances of error in the roof due to untrue shape of the shingles. lhave provided. a guide by means oi which a true forty-five degree anglecan be given to the shingle without reliance upon the unguided eye, andin which baclrlap is fixedly obtained. have provided a means forexpansion and contraction, and l have provided a guide for use inapplication of the attaching device. have thus substantially cut downthe undesirable points oi a roof which is confined positively in laying,and in use by inflexible securing devices, which have a definiterelation to two or more shingles, while preserv ing the good ones, whichare increase of area of exposure without danger of improper coverage,secureness of all units in place at all times, and protectionagainstcurling of the-exposed butts, and possibility of using a thinnermaterial of more flexibility and hence less expense to manufacture, aswell as easier to force to conform to irregulaiities of an old roof:surface.

Having thus described myinvention, what l claim as new and desire tosecure by Let ters Patent, is

l. A roofing unit formed of a shingle and an attaching device, havingtwo interspaced arms and a pocket forming portion to engage the cornerof a shingle thrust into it, from above, and said shingle being ofrectangular shape and having a series of edge nintilations arranged onlines crosswise of the shingle, and located inward from the cornersthereof to guide the position of the pocket formed portion of theattaching device.

2. A roof formed of shingles having general rectangular shape, and laidat an angle so that the corners of the shingles in a course are broughtacent to each other, attaching devices having arms nailed down to theadjacent corners of shingles in a course, said arms providing betweenthem for a pocket into which the corner of a superimposed shingle is tobe placed, said shingles 2 need with edge niutilations arrange inescrosswise of the shingles, and spaced nwardly from the edges so as todefine the position of the pocket forming element of p the attachingevice.

3. In a roofing unit for use with an attaching device of the characterdescribed, a body portion adapted to be laid with its edges at an angleto the roof lines, and said body portion having mutilations at its edgesarranged on lines at a like angle to the body thereof, for the purposeof indicating the lines of proper disposal of said unit with relation toother units on a root, said mutilations being spaced inwardly from thecorners of the shingle the distance of desired 1399mm Q overla of thecourses in a roof formed the opposite edge, same being erran ed inthereo lines across the shingle at a. like ang e, and 4. Inaroofing unitfor use with an attachsame being also placed inwardly from the 10 ingdevice of the character described, a body corners of the shin 1e adistance equal to the e 5 portion adapted to be laid with its edgesdesired overlap 0 the shingles when laid ,at an ang1e, said bodydportion having two in courses. v notches at one-edge an two projectionsat CHARLES L.
